The square-wheeled tricycle offers a smooth ride if you only choose your surface carefully.
As the video illustrates, the trike rides on a road of repeated pieces of an inverted catenary.
The square -wheeled trike, was built by the machine shop at the A&M Physics Department in Texas .
Is this amazing science, or what ?
